I am the proud owner of a set! Josh Dowling who early on help set up the Firewire production facility and then also Sunova and currently owns and operates Josh Dowling Shape, was generous enough to send me a set he had leftover.

For those that down't know, Herb has been around shape and creating some innovative concepts since the late 60's. The December '06 (I think) issue of SURFING magazine list's Herb directly after Steve Lis (who is credited for development of the fish shape) in their Surfing's Shaper Family Tree feature article. A copy of that tree can be found on Proctor's site, here.

Josh did a custom for a NorCal surfer, Mr. J . That board used the Supercharger system. The full board can be found here.. Pictures of the fins and the board above follow. In the picture I took of the fins, that's a quarter to the left. These are tiny little things.

The fins have a single FCS plug base and are set 1" outboard of the main fins. The are placed 1/2 their length ahead of the leading edge of the main fins and the cant and toe-in are to be 1/2 that of the main fins. The concept of the Superchargers, as I understand it, is that a slipstream is initiated, in which the main fin behind it creates less drag.
